Wrong 2: Filters are more reliable with longer lifespan
Fact: The function of the filter is to filter out dust and impurities in air, oil, fuel, and oil coolant, keeping the impurities away from the engine, protecting the engine system. High-quality and efficient filters are able to capture and filter out more impurities than those filters with low-efficiency and low-quality.
If the capacity of the two kinds of filters is similar, it is clear that the high-quality and efficient filters will be replaced more frequently. Some of the poor quality filters currently sold in the market are short-circuited (impurities are not filtered and directly go into the engine system). Filter paper perforation, poor bonding on the seam, poor bonding of the filter paper and end cover. If you use such a filter, maybe you can replace the filter in a very long time or even don't need to replace it. Because this kind of filters don't have the ability to filter the impurities.
